Good job!

I've rated the game as a beta in the overall game section as some pieces are of course not there yet.
On to the game....
Graphics: Need some spicing up. The terrain is nice and simple, but the flare effects get to be a little much at times. Also, the background is ugly.
Sound: Still a beta. There is none.
Gameplay: Very good. A little confusing at first, but once you get used to it, it's very fun trying to judge how much power is needed to get through a hole. Intuitive controls.
Story: Still a beta. There is none.
Interface: Could have used a menu at the beginning, and starts you off rather abruptly. Maybe include a tutorial in a future release?
Comments: All in all, this game is nice, even for a beta. It has great potential in future releases!
